Solution Overview

Problem

Existing tank valve devices are large in size due to intricate flow path configurations with multiple valves attached to a valve block.

Innovation Solution

The tank valve device and valve block are designed with the inlet/outlet and electromagnetic valve positioned outside the tank in one lateral direction, and the manual and safety valves positioned in two other lateral directions, gathering the flow path in the center to simplify the configuration and reduce size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple valves are attached to a valve block with intricate flow paths, then the valve device can perform multiple functions (electromagnetic control, manual operation, safety release), but the valve block becomes large in size

Engineering Contradiction:
Improvemulti-functionalityVSAvoidvalve block size
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The patent applies dimensional arrangement by positioning different valves in different lateral directions (first, second, and third lateral directions) extending from the tank. This spatial distribution in multiple dimensions allows the flow paths to converge at the tank port without requiring a large valve block, thus achieving multi-functionality while minimizing size.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent employs asymmetric positioning where the inlet/outlet and electromagnetic valve are disposed in a first lateral direction, while the manual valve and safety valve are positioned in second and third lateral directions respectively. This asymmetric arrangement optimizes the flow path convergence at the tank port and reduces the overall valve block size compared to symmetric configurations.

Inventive Principle:
Principle #4Asymmetry

2Volume of stationary object

If various valves and flow paths are integrated in a compact arrangement, then the valve block size is reduced, but the flow path configuration becomes more complex to design

Engineering Contradiction:
Improvevalve block sizeVSAvoidflow path configuration
Core Design Contradiction:
Volume of stationary objectVSDevice complexity

Solution Approach 1:

The patent segments the valve system by attaching different valves (electromagnetic valve, manual valve, safety valve) at different lateral positions relative to the tank. This segmentation allows each valve to have its own designated space while their flow paths converge at the tank port, simplifying the overall design compared to integrating all valves in a single compact block.

Inventive Principle:
Principle #1Segmentation

AI summary

This tank valve device includes: a valve block to be attached to a port of a tank and including an inlet/outlet for a fluid and a flow path connecting the inlet/outlet and the inside of the tank; an electromagnetic valve configured to open and close the flow path; a manual valve that stops flow in the flow path; and a safety valve that releases the fluid when a temperature outside the tank exceeds a predetermined temperature. The inlet/outlet and the electromagnetic valve are disposed outside the tank and positioned in the valve block in a first lateral direction that is one of the four directions from the valve block,. The manual valve and the safety valve are disposed outside the tank and positioned in the valve block in a second lateral direction and a third lateral direction, respectively, that are two of the remaining three directions.
